I agree. It is entertaining and they should race. Like I said, at the track he can request no time shown and it will be a real race witha a staging light and a light when the winner crosses the finish line. Gotta do it, everyone is wanting to see this.

NO ETA. See them running this all day long at the track near me.


Woot. my 30 PSI Hobbs switch just got here. Now I just need the upgraded fuel pump, and MSd stuff to try this bottle out.

Northstar still smokes. It's parked for the weekend and I'll be taking the Goose (Pontiac 6000) down to FL. Sorry to disappoint.

Punch the gas and feel the back step sideways; rip off a powershift and hear the tires punished by torque; downshift, lift off and feel the engine braking that comes only from big cubes, listen to the pop and gurgle. Know that you are driving an American V8. There are finer engines made, but none that are this cool.

Luck, Fate and Destiny are words used by those who lack the courage to define their own future

Ok we have into oct 8th for this race.... After that date my 4.9 will be getting converted to stick and undergoing a few more mods.... I still might hit the track reguardless so I can prove my ETA with a stock 4.9 powered by a auto th-440.... After that it's getting some nice aftermarket parts to add more ponnies........ This 79 TA turbo is just staring me in the face also But dats going on last.


And no I have not rated anyone on this subject because.... Hopely Punisher will still be active long enough so I can shove my stock 4.9 w auto ETA That will be faster then a mid 14secs down his throat

Does anyone else remember when this thread used to be about ETA's? It almost seems like a vague memory...

Jonathan/Shaun: You guys GOTTA get seperate UserNames, I'm getting as confused as someone talking to a two-headed psychopath...
Jon, you won some ebay auction from me some time ago (door panel) and I remember your F1McCreery website that even got a mention in SCC some time ago. I know you've been doing SCCA for some time, I'm sure you've got the chops to back up what you say. Nice car (I think yours is the Northstar powered number).
I remember Shaun being credited with a lot knowlege on the 2.8 by other members but I also understand that GM redesigned the 2.8 into the 3.1 because of the notorious poor oiling of the crank. I can't see how a 2.8 could endure a lot of abuse.
Now to be fair, I know some folks can get an undeserved bad rap; I've gotten the opportunity to meet, hang out with and work briefly with Steve Vincent (BVMotorsports) and Garth they took a lot of heat for doing the 4.9 a couple years ago, but I gotta say that car was FAST from the light! And that was before the final gear change and Rockcrawls' chip! No, we didn't take it to the strip, and Steve beat Jesse's 4.9 conversion Steve did for him first (very stock motor/trans but getting some mods now) in his Subaru WRX. Garth is in the process of building "The World's Fastest Naturally Aspirated V6 powered Fiero". No buildup thread, Garth doesn't post, It's going on in the Stealth Performance secret lab in Hampton. http://www.fiero.nl/forum/Forum1/HTML/027460.html
We all know there are really NO performance pieces for the 4.9 unless you make them yourself. Steve did Jesse's car I believe for $1600
A turbo on the 4.9 even with just the 2 lbs pressure seems to be a nice way to add top end although I've never been a big fan of turbos. http://www.fiero.nl/forum/Forum1/HTML/042758.html Maybe because the fastest turbocharged cars I ever drove were the 944 turbo when I sold Porsches, BMWs, VW, Mazdas and Audis in the 80's. Of those my favorite was the RX7 turbo witch was really smooth, just not as fast as you'd think. One of my favorite cars was the Mazda 323GTX, all wheel drive turbo-intercooled 5-speed what a hoot! It would run out of power around 85 MPH though but I could take cloverleafs at almost that speed.
Anyway, at the track I'm sure a smallblock would be the way to go, just ask Archie.
On the street and for my pocket, I'm leaning towards the 4.9. And just like you don't want people knowin' your times (why after all this posturing I don't know) I don't wanna drag race. I just want a car that is going to look good, run good, and let me whup on pretty much anything else on the street in a normal day.

Here. I thought i would overlay just one of my dyno runs against a 4.9 fiero. This was the against the highest 4.9 fiero I could find on that list. Some were much lower but this was the highest/ best power curve from a 4.9 that I could find on the link I posted earlier. I wanted to make this look as best for the 4.9 as I could so I used the best 4.9 dyno. Since the 4.9 dyno was only able to go to 5500 rpm thats where I had to stop my data input. Enjoy.

Edit here is the link for all the 4.9 swaps. AS you can see this was the best one in a Fiero http://www.etrackmasters.com/dynocharts.htm#Pont

This is the one of the car I took: http://www.etrackmasters.com/dyno/JackGu.gif

That's a good comparison. You see where the torque number comes in on the 4.9? That , is where the 4.9 will be gone by the time you get into your powerband. Torque is what gets you moving down the road , and off the line.
1/4 mile runs , the 4.9 will beat you off the line and then you will have to be playing catch-up , and you only have a 1/4 mile to do it. Ya'll go RUN !!

One must remember that this dyno wasn't Earl's car. his car could be making less or more then this dyno. Its just a comparo of the best dyno numbers I could find for a 4.9 and the mods for this 4.9 aren't listed. This 4.9 could have been stock or it could have been modified.

YOu also have to remember Ronnie that I am...

1. running a getrag 5 spd so I dont' have to launch just off idle. I hook best at a 3k rpm clutch drop
2. First gear on the getrag is real quick. I will be to 6k rpm in the blink of an eye.
3. my car is lighter then his so it wont' need as much hp/tq to get it off the line as quickly.
4. My car at 5k rpm is making(according to this dyno but remember the car is now making more then this) about 40 more hp. That 40 extra hp is going to make a huge difference in 1st gear as well as second gear. Not only that but I can wind the gear out farther to 6k and hold that powerband longer which will pay off esp in 3rd gear.

Here is another comparo.

If you do the math its quiet obvious.
